[ male announcer ] it's simple physics...

a body at rest tends to stay at rest... while a body in motion tends to stay in motion. staying active can actually ease arthritis symptoms. but if you have arthritis, staying active can be difficult. ex can help relieve arthritis pain but if you have arthritis, so your body can stay in motion. because just one 200mg celebrex a day ef so your body can stay in motion. for many with arthritis pain and inflammation. plus, in clinical studies, celebrex is proven to improve daily physical function so moving is easier. celebrex can be taken with or without food. and it's not a narcotic. you and your doctor should balance the benefits with the risks. all prescription nsaids, like celebrex, ibuprofen, naproxen and meloxicam have the same cardiovascular warning. they all may increase the chance of heart attack or stroke, which can lead to death. this chance increases if you have heart disease or risk factors such as high blood pressure or when nsaids are taken for long periods. nsaids, like celebrex, increase the chance of serious skin or allergic reactions or stomach and intestine problems, such as bleeding and ulcers,

which can occur without warning and may cause death. patients also taking aspirin and the elderly are at increased risk for stomach bleeding and ulcers. don't take celebrex if you have bleeding in the stomach or intestine, or had an asthma attack, hives, other allergies to aspirin, nsaids or sulfonamides. get help right away if you have swelling of the face or throat, or trouble breathing. tell your doctor your medical history. and find an arthritis treatment for you. visit celebrex.com and ask your doctor about celebrex. for a body in motion.

who are battling with such serious injuries. another major headline. the suspicious letter. investigators on capitol hill take no chances when a senator receives mail that tested positive for poison. it is wednesday, april 17th. >> announcer: from abc news, this is "world news now" with john muller and diana perez. we begin this half hour with important new clues in the boston bombing. abc news obtained the first images of what appears to be a mangled, parls partially exploded pressure cooker and the shredded backpack believed to have hidden that device. >> investigators have recovered a partial circuit board from that bomb. our coverage begins with chief correspondent brian ross. >> reporter: investigators at the crime scene have recovered the mangled remains of one pressure cooker bomb, which failed to completely explode according to officials briefed on the case.

and the fbi said, it is looking for a man who was carrying an unusually heavy black bag. >> the bag would have been heavy because of the component believed to be in it. >> reporter: the fbi has other clues in the videos. the white smoke seen after the detonation indicates a bomb built with low-velocity explosive mixtures, not military grade. >> they may not have had the resources as we've seen in other bomb attacks, but they knew how to make the bomb go boom. >> reporter: experts say the large pieces of metal as seen here in the air, suggests the bombs may have been concealed in a mail box or trash barrel, as one witness describes. >> i saw the garbage barrel explode and the flash, the fire, the smoke and i just ran as fast as i could. >> reporter: mike sullivan is the former head of the atf. >> all the evidence they collect may not look like much, but for the investigators every small

piece of evidence they collect is going to be a treasure-trove. >> reporter: if the fbi belief about the pressure cooker bears out, it will be no surprise to counterterrorism officials who have warned about their possible use with readily available components for years. there are numerous descriptions online about how to build a pressure cooker bomb, including this detailed one posted in an al qaeda internet publication. but april is also a month with significance for domestic terror groups. the months of the waco raid and the oklahoma city bombing. as president obama made clear, there is still no evidence of who is responsible for this act of terrorism. >> this was a heinous and cowardly act and given what we now know about what took place, the fbi is investigating it as an act of terrorism. >> reporter: fbi agents tell abc news they have what they call tons of video of what happened that day and they are confident that somewhere on that video somewhere is a picture of the person who planted those two bombs. brian ross, abc news, boston.

and we're learning more about the bystanders killed in the bombing. one victim identified as a female boston university student from china who was attending the race with friends and friends and neighbors gathered at a vigil last night in the dorchester neighborhood where the youngest victim lived. third grader martin richard was remembered as a vivacious boy who loved to run, climb and play sports. a friend describes the close-knit family. >> whenever we would see them, they would all be together. whether it was at church, going to school, on the sports field, in the neighborhood and they were a very active family in our community, pillars of the community. an overused term, but not in this case. >> martin's mother suffered serious injuries in the blast and his 6-year-old sister lost a leg. also being remembered, 29-year-old krystle campbell. killed at the finish line with her best friend. her dad remembered him as the light of his life. her mother appeared on the family doorstep yesterday telling everyone that the couple

is heartbroken at the loss of their child. >> couldn't ask for a better daughter. we can't believe this is happening. such a hard worker in everything she did. this doesn't make any sense. >> krystle's best friend suffered a severe leg injury. almost an understatement to say boston is in grief, especially after learning more about the victims of the bombing. >> our coverage continues live with marci gonzalez. marci, the student from boston university. we know so little about her. what can you tell us? >> john, you basically covered everything we know. she was a graduate student at boston university and she was from china but we don't know her name, her age, what she was studying. we're told that's because her family doesn't want any of her personal information released. >> and marci, moving on to the people we do know a lot about, clearly this is a city that is in mourning. such an enormous crowd at that

vigil last night in boston common for the little boy and all the others that were lost. >> one vigil for the 8-year-old boy and then a separate vigil in boston common just a few hundred feet from where i am standing. hundreds of people galthered. they lit candles and sang songs and they call this vigil peace here and everywhere. it was really just one way of this community coming together and grieving. it is just one of the very many vigils and services going on here in boston this week. of course, president obama will be here on thursday for an interfaith service. >> marci, it has been a day and a half since the bombings, what are you noticing about security right now? >> a very noticeable increase. the number of national guardsmen has doubled since race day. 1,000 national guardsmen here in boston. just an hour or so ago i took a walk and went a few blocks and we saw police officers on almost

every corner. also mass transit they were doing random bag searches. so, a very noticeable increase to security here in the city. >> marci gonzalez reporting live from boston this morning, thank you. the remembrances in boston will continue all week long. as marci mentioned tomorrow president obama will travel there where he will speak at an interfaith service. after meeting with domestic security team yesterday, the president went a step further than he did on monday, repeatedly calling the bombings an act of terrorism. >> any time bombs are used to target innocent civilians, it is an act of terror. what we don't know yet know, however, is who carried out this attack and why and whether it was planned and executed by a terrorist organization, foreign or domestic, or was the act of an individual. >> president obama also repeated his promise that those

responsible for monday's attack will be brought to justice saying, "the american people refuse to be terrorized." the senate intelligence committee received a full briefing on the bombing last night and the investigation surrounding it. when it was over saxby chambliss told the government it may lead the government to reevaluate security at major events. so many of which are considered soft targets. he also suggested new assistance might be offered to prominent events that attract huge crowds. this is still such an incredible time for the people of boston as they try to recover from these events and the nation is now becoming a part of this recovery for them. >> no doubt about it. coming up, how boston's grief is turning into national grief with a show of support. also this morning, most bostonians are known for their strong will and community pride, and you hear how so many people are willing to carry on, despite such a tragedy. and, first, the scare on capitol hill. the letter laced with poison sent to a well-known lawmaker. the investigation, the suspect and the precautions. you're watching "world news

such scares have happened in washington before. in 2004, a letter containing ricin powder shut down three senate offices for two days. extraordinary precautions were taken to keep senators and staff safe. in 2003, the secret service revealed, president george w. bush received a letter containing a vial of ricin. no one was harmed in any of the cases. in this latest case, no word on anyone becoming sick. there is no indication this is tied to the boston terror scares. pierre thomas, abc news, washington. >> what is most important about the story, field tests are notoriously inaccurate. once again the potentially fatal powder, substance, ricin is now being sent, letter is being sent to a lab to make sure what they found perhaps is nothing or could be this particular -- >> more sophisticated tests. hopefully will conclude something else. right now does look like it could be. >> that's right.
